    Fundamentals of Electrochemical Impedance Spectroscopy and Application to Li-Ion Batteries

    Electrochemical Impedance Spectroscopy (EIS) is a high-information content technique that provides insight into complex systems. EIS has gained tremendous popularity since innovation with the line of Frequency Response Analyzers from Solartron Analytical – but remains intimidating to many users. Join this webinar to gain confidence in your understanding of the technique itself and its application to the Li-Ion battery activity chain. EIS is used to: 1.) study diffusion characteristics and SEI formation during material development, 2.) identify degradation modes, ESR, State-of-Charge during cell characterization, and 3.) rapid grade State-of-Health during modules evaluation.

    This webinar will focus on the following key topics:

    • Fundamentals of data acquisition and data analysis of EIS
    • How EIS theory is applied in practice by beginners and experts
    • The value of EIS as a tool in evaluation of Li-ion batteries
    • How AMETEK’s portfolio meets uniquely defined needs at different points of the value chain

    Passive Mitigation of Thermal Runaway Propagation in Dense 18650 Lithium Ion Cell Assemblies

    Utilization of lithium ion batteries (LIBs) in various applications has been growing exponentially. LIBs offer some distinct advantages including high energy density, outstanding efficiency, long lifespan, and fast charging capability. Probably, the main disadvantage of LIBs is that a small deviation from normal operating condition may result in rapid self-heating accompanied by ejection of large quantities of flammable materials, which can cause fire or explosion. The failure process becomes more dramatic when many cells are arranged in large arrays in order to fulfill the power requirements by most of applications. Failure of a single cell can release sufficient energy to trigger failure into adjacent cell, which subsequently propagates throughout the entire array. In this webinar, a set of passive strategies to mitigate failure propagation will be presented. The dynamics, heating rates, gaseous emissions, and energetics of thermally induced thermal runaway propagation in dense arrays consisting of 12-15 fully charged 18650 lithium ion cells have been quantified to determine the effectiveness of these passive mitigation strategies.

    This webinar will focus on the following key topics:

    • Thermal runaway in lithium ion batteries
    • Thermal runaway propagation in lithium ion battery packs
    • Hazards associated with failure propagation
    • Passive mitigation strategies

    XRF Analysis in Process Control of Battery Cathode Manufacturing

    To optimize the chemical composition of the final cathode materials, it is first essential to control the chemical composition of the precursor and raw materials. X-ray fluorescence (XRF) analysis, which can characterize chemical composition and impurities from just a few ppm all the way up to 100%, is the best technique for controlling this parameter.

    Specifically, XRF provides a simpler and more accurate way of measuring elemental composition than inductively coupled plasma (ICP) mass spectrometry, as it does not require any sample dilution or acid digestion.

    Malvern Panalytical specialists have developed a turn-key solution, including certified reference materials (CRMs) and calibration templates, for the analysis of both precursor and cathode material composition with the benchtop Epsilon 4 EDXRF or floor-standing Zetium WDXRF spectrometers.

    This webinar will focus on the following key topics:

    • On-line and at-line XRF analysis of solutions containing Ni, Co and Mn
    • NCM-certified reference materials for XRF calibration purposes
    • Turn-key solution for the XRF analysis of NCM precursors and cathodes
